Description
- This application is a continuation of U.S. patent application Ser. No. 15/952,207, filed Apr. 12, 2018, the entire contents of which are incorporated by reference herein.
- Recent advances in surgery focus on minimally invasive techniques, which utilize smaller and/or a fewer number of incisions, and can eliminate the need in previous techniques to detach or sever muscular tissue. For example, minimally invasive hip replacement surgery utilizes entry at the anterior of the leg of a patient. This point of entry allows a surgeon to perform a hip replacement procedure while only making a single incision of about four inches in length, rather than multiple incisions or incisions of ten inches in length as in prior procedures. Further, muscles within the leg are not damaged through detachment or severing in these procedures, resulting in a much faster recovery time. These procedures still require access to the acetabulum, which must be reamed before insertion of the prosthesis. Further, proper manipulation and positioning of the femur is essential in carrying out the anterior approach hip replacement surgery.
- Disclosed herein is a u-style drape that covers a torso and/or a head portion of a patient. During use of this first u-style drape, wherein the surgical site is located, a second u-style drape is placed over or under this first u-style drape. Unlike the first u-style drape, the second u-style drape covers the patients waist, both legs, and feet. The two drapes overlap, with the u-shape of both the drapes intersecting at the surgical site. The two drapes are aligned and positioned by a user such as a physician to provide access through the drapes to the linear incision length needed for the particular surgery. In one embodiment, the drape disclosed in the present application is symmetrical along the longitudinal center line so it can be used for either left hip or right hip surgery.
- In one example embodiment of the drape, the drape may comprise a top surface and an opposite bottom surface; wherein the bottom surface is configured to contact a first user (i.e., a patient), and the top surface is configured to engage with a second user (i.e., a physician). The drape may further comprise at least one sleeve extending perpendicularly from the top surface. The at least one sleeve, which is sealed to separate the top surface of the drape from the bottom surface of the drape, may further include an opening extending from the bottom surface to an interior of the at least one sleeve. The drape may further comprise at least one flap extending perpendicularly from the top surface, wherein the at least one flap is configured to form a secondary barrier by wrapping around a first device and the at least one sleeve. The first device may be a femoral support hook. The drape may further comprise a first opening corresponding to an incision site, wherein the first opening may be in a u-shape configuration or in a window cut-out configuration.
- In one example embodiment, a method of packaging a drape is disclosed. The drape may be packaged by folding the drape that includes at least the components described herein.
- The foregoing summary, as well as the following detailed description of the invention, will be better understood when read in conjunction with the appended drawings.

FIG. 1 illustrates a perspective view of a medical table with a patient positioned on the table. Apatient 102 undergoing a knee or hip arthroplasty surgery typically will be anesthetized for surgery then placed on the surgical table 100. The back of the patient will be placed on aplatform portion 104 of the table, with thelegs spars traction setting mechanism 116 for applying a desired amount of force on the foot of the patient. Thehip 118 of the patient is placed adjacent to a pivot connection between theplatform portion 104 and thespars right leg 106. Traction boots 120, 122 can be used to ensure traction via the traction system. A manual or electrically poweredsurgical table jack 124 can be used to raise and lower afemoral support hook 126. Thefemoral support hook 126 being connected to thetable jack 124 by anangled bracket 128. The manual or electrically poweredsurgical table jack 124 may also correspond to a femur lift mechanism. - The raising and lowering of the
jack 124 can be accomplished via the rotation or arotatable shaft 130, the motion of which is indicated bydirectional arrow 132. Theangled bracket 128 is also capable of rotating relative to thejack 124, such that the surgeon performing the surgery can rotate thehook 126 into and out of position, providing complete control of the positioning of theangled bracket 128 relative to the femur of theright leg 106. The end portion of thehook 126 being shaped to receive and support the femur during the procedure. An appropriate hook is described in U.S. patent application Ser. No. 10/930,809, entitled “Surgical Support for Femur,” to Joel M. Matta et al., filed Sep. 1, 2004, issued as U.S. Pat. No. 7,824,353, which is hereby incorporated herein by reference. There can be a hook and corresponding components on each side of the table, one for each leg, in order to allow for operation on either side of the patient. - In operation, the surgeon places a base portion of the
femoral support hook 126 into an appropriate opening on theangled bracket 128. Theangled bracket 128 has a plurality of openings for receiving the base portion, in order to position the receiving end of thefemoral support hook 126 at an appropriate distance from the femur to be supported. At the proper time after an incision is made in the patient, thefemoral support hook 126 on the appropriate side can be swung into position in the wound at the hip region of the patient, and can be positioned to support the femur. The surgeon (or an assistant) then can adjust thejack 124 to properly angle and support the femur such that the surgeon can gain unrestricted access to the acetabulum and other portions of the hip in order to accomplish, for example, an artificial hip replacement for the patient. When the support of the femur is no longer needed, the support including thefemoral support hook 126 can be lowered using thejack 124, and then swung from the wound in the patient and moved outwardly by the rotation of theangled bracket 128 relative to thejack 124, as shown bydirectional arrow 134. Theangled bracket 128 then can be removed or left in this position as surgery progresses and is finished. - Now referring to
FIG. 2 , a perspective view of thefemoral support hook 126 used in the medical table ofFIG. 1 is described. Afemoral support hook 126 can be positioned on either side of the table 100 for supporting a respective femur. Thefemoral support hook 126 can be attached via anangled bracket 128 to an appropriate vertical positioning system or lift, such as amotorized jack 203. Such a surgeon-controlled femoral power lift can enable hyperextension of the hip for improved surgical access. Proper placement allows the surgeon to effect hip replacement without the femur obstructing access to the acetabulum of the hip. The vertical positioning system can include a base portion designed to attach to the table, or to be fixedly positioned with relation to the table. Although a manual jack of the type described in connection withFIG. 1 may also be used, an advantage to using amotorized jack 203 is that the surgeon can control the jack directly, such as through use of a remote control device, which can avoid any potential communication problems between the surgeon and an assistant turning a crank for a jack in previous systems. - Motorized jacks, which can be controlled by the surgeon through a base control unit, a remote control unit, or a foot pedal, can be used to raise and lower the appropriate
femoral support hook 126. Eachangled bracket 128 can be rotated relative to therespective jack 124 and the respectivemotorized jack 203 such that the surgeon performing the surgery can rotate the hook into and out of position, providing complete control of the positioning of thefemoral support hook 126 relative to the femur. Themotorized jack 203 and control mechanism can include any appropriate devices known or used in the art for imparting a controlled amount of linear motion. As seen in the embodiment ofFIG. 2 , one embodiment of thejack 124 can include atelescoping member 204 controlled by arotary drive motor 205, and a square shapedpost 206 that extends from thetelescoping member 204. Thepost 206 is configured to engage with a metal sleeve of theangled bracket 128 such that theangled bracket 128 is affixed and/or snap-fitted on to thepost 206 for use during a surgical procedure. This metal sleeve of theangled bracket 128 extends over thesquare post 206 and covers therespective sleeve femoral support hook 126 and theangled bracket 128 may be sterile, whereas themotorized jacket 203, thetelescoping member 204, squareshaped post 206 may not be sterile. - In alternative embodiments, the position of the
femoral support hook 126 in theangled bracket 128 and/or the rotation of theangled bracket 128 can be accomplished through sliding mechanisms, or can be automated through use of a motorized device. These adjustments then could be accomplished by the appropriate control mechanism available to the surgeon and/or assistant. - In operation, the surgeon can place a base portion of the
femoral support hook 126 into an appropriate opening on theangled bracket 128. Theangled bracket 128 has a plurality of openings for receiving the base portion of thefemoral support hook 126, in order to position the receiving end of thefemoral support hook 126 of the femur at an appropriate distance from thefemoral support hook 126 to be supported. At the proper time after an incision is made in the patient, thefemoral support hook 126 on the appropriate side can be swung into position in the wound at the hip region of the patient, and can be positioned to support the femur. The surgeon (or an assistant) can then cause thejack 124 to properly angle and support the femur, by operating a foot pedal or control mechanism (not shown) as discussed above, such that the surgeon can gain unrestricted access to the acetabulum and other portions of the hip in order to accomplish an artificial hip replacement for the patient. - Next, referring to
FIG. 3 a perspective view of a top side orsurface 301 of one embodiment of asurgical drape 300 is shown that is configured to be used with a surgical table 100 shown inFIG. 1 andFIG. 2 . Thedrape 300 is shaped and sized to cover at least a torso and a head portion of a patient. In this embodiment, thetop surface 301 of thesurgical drape 300 is generally rectangular in shape with aproximal end 300A and adistal end 300B, and with varying width and length dimensions. One skilled in the art would appreciate that thesurgical drape 300 may not be limited to a rectangular shape and in other embodiments may take other configurations such as a square shape. During use, thetop surface 301 is the surface that is facing and may be in contact with the physician or surgeon performing the surgical procedure. Thetop surface 301 may include the following: au-shaped opening 305; at least oneflap sleeve u-shaped opening 305; the at least oneflap sleeve proximal end 300A of thetop surface 301 of thedrape 300; and the at least one marking 302 is by thedistal end 300B of thetop surface 301 of thedrape 300. Thetop surface 301 includes au-shaped opening 305 on itsproximal end 300A. Theu-shaped opening 305 corresponds to the incision site as to where a physician will make an incision for purposes of performing a surgical procedure. Theu-shaped opening 305 allows for the physician to perform its desired surgery by maneuvering his or her surgical tools in and around theu-shaped opening 305. Thedrape 300 may be used in conjunction with a second drape (not shown) having a u-shaped opening. The second drape may cover the remaining exposed portion of the patient's legs, with the u-shaped portion of the second drape overlapping the u-shaped portion of thedrape 300. By adjusting the location of the second drape, the portion of the patient that is exposed by the intersecting u-shaped cutouts may be increased or decreased based on the needs of the surgeon. - One skilled in the art would appreciate that the
u-shaped opening 305 is for illustrative purposes only. In an alternative embodiment, the drape may be sized to cover the full body of the patient. In these embodiments, rather than au-shaped opening 305, the drape may include a window. Thedrape 300 could be configured to have a surgical site opening similar to the opening disclosed in U.S. patent application Ser. No. 15/912,530, filed on Mar. 5, 2018, which is incorporated herein by reference. Alternatively, thedrape 300 could be configured such that thedrape 300 covers a lower portion of a patient, and theu-shaped opening 305, the at least oneflap sleeve - Still referring to
FIG. 3 , thetop surface 301 of thedrape 300 includes at least afirst flap 303A, asecond flap 303B, afirst sleeve 304A and asecond sleeve 304B. These aforementioned features are positioned by theproximal end 300A of thedrape 300 and adjacent to theu-shaped opening 305. As shown inFIG. 3 , the first andsecond sleeves second flaps top surface 301. The first andsecond sleeves second flaps second sleeves FIG. 2 ). - The
first sleeve 304A may have a height that is the same, similar or different to a height of thesecond sleeve 304B. Likewise, thefirst flap 303A may have a height that is the same, similar or different to a height of thesecond flap 303B. However, height of the first andsecond flaps second sleeves FIG. 3 . The first andsecond flaps second sleeves FIG. 3 , thefirst flap 303A is positioned in front of thefirst sleeve 304A such that thefirst flap 303A in a sense obstructs thefirst sleeve 304A from theu-shaped opening 305. Similarly, thesecond flap 303B is positioned in front of thesecond sleeve 304B such that thesecond flap 303B in a sense obstructs thesecond sleeve 304B from theu-shaped opening 305. Thefirst flap 304A and thesecond flap 304B are spaced apart on thetop surface 301 and are generally adjacent to, and separated by, theu-shaped opening 305 as shown. - Lastly,
FIG. 3 shows at least one marking 302 on adistal end 300B of thetop surface 301 of thedrape 300. The marking 302 may represent a hand symbol that is holding thetop surface 301 of thedrape 300 and the direction of arrows which instruct a physician or user to pull thedrape 300 in a certain direction. For example, marking 302 illustrates direction of arrows in one direction that instructs the physician how to unfold thedrape 300 once taken out of its packaging. - Next, referring to
FIG. 4 , a perspective view of an embodiment of a back side orsurface 306 of asurgical drape 300 is shown. Theback surface 306 of thedrape 300 is opposite to thetop surface 301 of thedrape 300 as shown inFIG. 3 . During use, the back surface is the surface that is facing and/or in contact with the patient. Theback surface 306, unlike thetop surface 301, includes at least twomarkings u-shaped opening 305. Thesemarkings drape 300 on the patient. For example, as shown inmarkings distal end 300B and feet facing theproximal end 300A. Such markings allow the physician to orient thedrape 300 accordingly during the surgical procedure. As shown inFIG. 4 , themarkings u-shaped opening 305. One skilled in the art would appreciate that themarkings u-shaped opening 305 on thebottom surface 306 of thedrape 300 may include an adhesive tape 305-1A, 305-1B and 305-1C. These are positioned around the edges of theu-shaped opening 305 such that upon use of the drape the adhesive tape 305-1A, 305-1B, 305-1C can be affixed to a patient's skin prior to surgery. Thereby, ensuring that thedrape 300 is in place and does not move or reposition during a surgical procedure. In order to apply the adhesive tape 305-1A, 305-1B, 305-1C to a patient's skin, a protective outer covering may be first removed such that the underlying adhesive surface is exposed in order to firmly secure thedrape 300 to the patient's skin. - Now
FIGS. 5 and 6 will be discussed in detail.FIG. 5 illustrates a first or asecond sleeve top surface 301 of thedrape 300. The first andsecond sleeve FIG. 4 , the hollow cavity extends from thebottom surface 306 of thedrape 300 to the length of therespective sleeve sleeve bottom surface 306 of thedrape 300 and the structure placed inside of thesleeve top surface 301 of thedrape 300. This hollow cavity allows for therespective sleeve post 206 shown inFIG. 2 such that the base of the respective sleeve is roughly co-planar to the top surface of thepost 206. - In further embodiments, the first and
second sleeve second handles respective sleeve second handles respective sleeve top surface 301 of thedrape 300. Thehandles drape 300 andsleeve second handles respective sleeve post 206 shown inFIG. 2 . The rigid nature of thehandles sleeve post 206 without ripping or otherwise damaging the drape or sleeve. It is noted that handles 501A, 501B inFIG. 5 are shown in a curve shape only for illustration purposes, however, thehandles handles respective sleeve -
FIG. 6 represents a closer view of the sleeve shown inFIG. 5 . In addition tohandles flange 901 is illustrated inFIG. 6 . Theflange 901 may be an extended portion of thesleeve bottom surface 306 of thedrape 300 opposite to the hollow interior cavity of therespective sleeve flange 901 may be bonded to thebottom surface 306 of thedrape 300 using pressure sensitive adhesive, heat seal adhesive and/or ultrasonic sealant. Thereby, securing thesleeve bottom surface 301 of thedrape 300. Such securing mechanism provides strain relief to help prevent a tear or rip in thedrape 300, especially around regions of therespective sleeve respective sleeve post 206. Theflange 901 may be further affixed to the bottom surface of thedrape 306 by an additional annular layer of adhesive covering theflange 901. - Next referring to
FIG. 7 , a top view of thetop surface 301 of an embodiment of thedrape 300 is illustrated. As shown inFIG. 7 , same components as discussed above are included on thetop surface 301 of thedrape 300. That is, as discussed before, thetop surface 301 includes the following—afirst flap 304A, asecond flap 304B, afirst sleeve 304A, asecond sleeve 304B, and au-shaped opening 305. Further, as represented by dotted lines,markings bottom surface 306 of thedrape 300. - Next,
FIGS. 8 and 9 will be discussed.FIG. 8 illustrates a cut out or a segment of thetop surface 301 of one embodiment of thedrape 300, wherein only thesecond sleeve 304B and thesecond flap 303B are shown. As shown inFIG. 8 , and discussed previously, thesecond sleeve 304B and thesecond flap 303B extend or protrude generally perpendicularly from thetop surface 301 of thedrape 300. Theflaps respective sleeve respective sleeve drape 300 is breached during installation of theangled bracket 128 or otherwise compromised by accidental pulling or tugging of thedrape 300. -
FIG. 9 illustrates an embodiment showing a detailed view of thesecond flap 303B and thesecond sleeve 304B. As shown inFIG. 9 , thesecond flap 303B is generally perpendicular to thetop surface 301 of thedrape 300, and includes three sides. The three sides may form a shape of a rectangle or may have a similar configuration as appreciated by one skilled in the art. The sides or edges of thesecond flap 303B are represented as 303B1, 303B2, 303B4, 303B5 and 303B6. The middle section of thesecond flap 303B that forms the body of the same is represented as 303B3. The side or edge 303B4, 303B5 is parallel to the side or edge 303B1, 303B2. The side or edge 303B6 is perpendicular to the sides 303B4 and 303B1 as shown inFIG. 6 . In particular, sides or edges 303B4, 303B6 and 303B1 may have adhesive tape positioned on them. When ready to be used, a user, such as a physician or technician, may remove a protective outer covering from the adhesive tape such that underlying adhesive surface is exposed. The protective outer covering protects the adhesive surface from sticking to unwanted surfaces prior to when thedrape 300 is ready for use. - It is important to note, as shown in
FIG. 9 , that in certain embodiments, the length of the adhesive tape on the edge 303B4 may be longer than the length of the adhesive tape on the edge 303B1. As illustrated further inFIG. 16F (discussed below), thesecond flap 303B is folded back on itself as indicated byarrow 303B-1 (shown inFIG. 8 ). The folding back of thesecond flap 303B results in—(i) the edge 303B4 folding back on itself to form a second barrier on thedrape 300 and theangled bracket 128 as the adhesive tape on the edge 303B4 attaches to itself and/or to thedrape 300; (ii) the edge 303B1 folds back on itself to form a second barrier on theangled bracket 128 and thedrape 300 as the adhesive tape on the edge 303B1 attaches to itself and/or thedrape 300; and (iii) the adhesive tape on the edge 303B6 attaches to thedrape 300. The edges represented by 303B5 and 303B2 are edges of thesecond flap 303B that do not include adhesive tape. As illustrated further inFIG. 16F (discussed below), part of theangled bracket 128 extends through therespective flap angled bracket 128 is covered by therespective flap - It is noted that the above discussion is made with respect to the
second flap 303B; however, same features, orientation and components also similarly apply to thefirst flap 303A. One skilled in the art would appreciate to interpret thefirst flap 303A having the same features as thesecond flap 303B. Further, one skilled in the art would appreciate that therespective flaps second flap 303B may be used, and if a right hip is being operated, thefirst flap 303A may be used. The use of twodifferent flaps drape 300 either for a right hip surgery or a left hip surgery. However, thedrape 300 may only be used for a single procedure at a time. That is, either performing a right hip surgery or a left hip surgery. As such, certain example embodiments of thedrape 300 may include only a single flap and a single sleeve for use in a specific hip (right or left) surgery. - Now referring to
FIGS. 10 and 11 .FIG. 10 represents a marking positioned ontop surface 301 of an embodiment of thedrape 300 by thedistal end 300B of the drape. As discussed above with respect toFIG. 3 , the marking 302 may represent a hand symbol that is holding thetop surface 301 of thedrape 300 and the direction of arrows which instruct a physician or user to pull thedrape 300 in a certain direction. For example, marking 302 illustrates direction of arrows in one direction that instructs the physician how to unfold thedrape 300 once taken out of its packaging. One marking 302 is shown in the figures, however, one skilled in the art would appreciate that multiple markings of similar character or representation may be undertaken. - Referring to
FIG. 11 , in certain embodiments, a different type of marking 307A, 307B is represented. As discussed above with respect toFIG. 4 ,markings drape 300 on the patient. Discussion set forth above with respect toFIG. 4 is reiterated here. One skilled in the art would appreciate that themarkings - Next,
FIGS. 12 and 13 will be discussed.FIG. 12 represents an embodiment of the final package that may be manufactured as an end product. Thepackage 1200 includes thedrape 300 in a folded configuration that is protected by an outer envelope as represented by 1300 shown inFIG. 13 in order to protect or maintain the sterility of thedrape 300 as it is deployed from a folded configuration. That is, thedrape 300 in a folded configuration with an outer envelope, represented as 1300, is positioned or placed inside thepackage 1200 before being shipped or sold to a final user or customer. One skilled in the art would appreciate that theentire drape 300, theouter envelope 1300, and the inside of thepackage 1200 may be made sterile before being shipped or sold. The arrow represented inFIG. 13 illustrates the removal of the foldeddrape 1300 from thepackage 1200. - In certain embodiments, the
package 1200 may be a chevron pouch. One skilled in the art would appreciate that a chevron pouch is a type of device packaging that features an entire peel-able side 1202 with a seal shaped like achevron 1201. It is used most often for sterile medical products that do not require rigid packaging. Use of chevron package prevents sterile components from becoming non-sterile. Thepackage 1200 may further include alabel 1203 with instructions ofuse 1204. The instructions ofuse 1204 inform a user how to use thedrape 300. One skilled in the art would appreciate that theentire drape 300, theouter envelope 1300, and the inside of thepackage 1200 may be sterile. - Now one embodiment of the method of folding the
drape 300 will be described with respect toFIGS. 14A-15C . These steps may be performed by a manufacturer of the drape or an end user of the drape. As shown inFIG. 14A , thedrape 300 is positioned with its top surface facing a user. A preliminary step may include the user taping down theflaps flaps flaps top surface 301 of thedrape 300, and away from thesleeves flaps flaps sleeves - Next, as shown in an embodiment in
FIG. 14B , the proximal most ends 300A1, 300A2 of thedrape 300 may be folded in a three-fold fashion. This is achieved by first having the proximal most end 300A1 folded up to theflap 303A and then folding the proximal most end 300A1 back on itself. Similarly, the proximal most end 300A2 is folded up to theflap 303B and then folded back on itself. Thereby, folding the proximal most ends 300A1, 300A2 on thetop surface 301 of thedrape 300 in a three-fold fashion. The corners 305-2 of the proximal most ends 300A1, 300A2 are flipped back such that thebottom surface 306 of thedrape 300 is exposed with the adhesive tape 305-1 along theu-shaped opening 305 faces the user. - Now referring to another embodiment shown in
FIG. 14C , the next step in the folding process of thedrape 300 may include taking the ends 300A3, 300A4 of thedrape 300 and folding them inward towards the center of thedrape 300. The ends 300A3, 300A4 represent the right and left sides of thedrape 300. During this folding procedure, the ends 300A3, 300A4 are brought in towards the center of thedrape 300 up to the point where theflaps top surface 301 of thedrape 300. The folding of theends FIG. 14D . - Next, multiple accordion folds may be done to the
top surface 301 of thedrape 300 such that thedistal end 300B is placed on top of theproximal end 300A. The accordion folds are achieved by finding an approximate mid-point on thetop surface 301 of thedrape 300 and having thetop surface 301 fold on itself in an accordion fashion such that thetop surface 301 is stacked upon each other as shown in an embodiment inFIG. 14E . The stacking of thetop surface 301 on top of each other is resultant of the accordion fold performed by the user to thetop surface 301. It is important to note that after the accordion fold is completed, thedistal end 300B of thedrape 300 may be folded back on itself such that thetop surface 301 of thedrape 300 with the marking 302 is exposed to the user. The marking 302, as discussed above, may represent a hand symbol with direction of arrows that instruct a user, such as a physician, to pull thedrape 300 in a certain direction. - Now referring to an embodiment shown in
FIG. 15A , the cross-section of the accordion folds as illustrated inFIG. 14E is shown. The next step is to have theends drape 300 in the accordion fold to be folded towards each other, parallel to thetop surface 301 of thedrape 300 such that theends drape 300. The central axis of thedrape 300A as shown inFIG. 15A is represented by “A”. Lastly, and the final fold, is to have theends FIG. 15B . Such a book-like configuration allows thedrape 300 to be put together in a compact fashion that is easy to handle by the user. In this final configuration, shown inFIG. 15B , the adhesive tape 305-1A, 305-1B, 305-1C, on thebottom surface 306 of thedrape 300 and themarkings markings drape 300 with respect to the patient. - In summary,
FIGS. 14A-15B represents one example embodiment of an overall folding process of thedrape 300 from start to finish such that thedrape 300 can be packaged in a chevron pouch. - Now, an embodiment of the method of using the drape 300 (i.e., deploying the drape) will be described with reference to
FIGS. 16A-F . Upon obtaining thepackage 1200 and after reading the instructions ofuse 1204, a user may open thepackage 1200, a chevron package. Upon disassembling thepackage 1200, the user may retrieve the folded drape with anouter envelope 1300 from thepackage 1200. At this point only the sterile portions (i.e., thebottom surface 306 of the drape 300) are in contact with the inner lining of thepackage 1200. In order to ensure that the sterile portions of the drape are not contaminated, the user follows close protocol in retrieving the foldeddrape 1300 out of thepackage 1200 and disassembling the same. - Once the
drape 300 is unfolded, without contaminating the steriletop surface 301 of thedrape 300, the user identifies themarkings bottom surface 306 of thedrape 300. Thesemarkings drape 300 with respect to the patient. Upon identifyingsuch markings u-shaped opening 305 of thedrape 300 along the incision site of the patient'sleg 108, as shown inFIG. 16A , such that the physician has a working space to make the desired incision as needed to perform the surgical procedure. After aligning the window cut-out or theu-shaped opening 305 along the incision site, the user may adhere thedrape 300 to the patient using edge 305-1B of the tape along the edges of theu-shaped opening 305 on theback surface 306 of thedrape 300. This step allows thedrape 300 to be positioned in place and prevent it from being maneuvered or displaced during the deployment of thedrape 300 before the tape strips around the edges 305-1A and 305-1C of theu-shaped opening 305 are used for final affixation to the patient. The user may then deploy thedrape 300 by letting theends FIG. 15A , to unfold. In other words, the folded ends 1501, 1502 are allowed to unfold along their respective direction in which they were folded. - Thereafter, the user may identify the
mark 302 on thetop surface 301 which indicates to the user to pull thedrape 300 in a certain direction. As shown inFIG. 16B , thedistal end 300B of thedrape 300 is pulled in a direction towards the patient's torso and head such that thebottom surface 306 of thedrape 300 covers the patient. Next, as shown in an embodiment shown inFIG. 16C , twoarbitrary points drape 300 may be identified and clipped onto two separate pins or hooks 1603, 1604. As shown inFIG. 16C , each point on the drape is connected or affixed to a respective pin orhook drape 300 are unfolded such that arms of the patient are covered or protected under thedrape 300. And, ends 300A1, 300A2 of thedrape 300 are unfolded to protect or cover at least a portion of the legs of the patient. Thereby, ensuring theu-shaped opening 305 is positioned on or around the incision site of the surgical procedure while the remaining portions of the drape cover the patient in order to maintain sterility and avoid contamination. As shown in an embodiment shown inFIG. 16D , the resulting configuration of the deployeddrape 300 is achieved, wherein thebottom surface 306 of thedrape 300 contacts the patient while thedrape 300 is securely positioned and oriented by pins or hooks 1603, 1604, and the arms and legs of the patient are covered under the drape. In turn, ensuring sterility of the surgical site and the instruments used during the surgical procedure is maintained. - Next, the user may peel-off a protective outer covering of the adhesive tape 305-1A and 305-1C that runs along the edges of the
u-shaped opening 305 from thebottom surface 306 of thedrape 300. By peeling-off the protective outer covering, the adhesive sticky portion underneath the protective outer covering would be exposed which would allow the user to affix or firmly engage thedrape 300, especially the u-shapedsurgical opening 305, to the patient. One of ordinary skill in the art will appreciate that other methods of affixing the drape to the patient during unfolding may be used, either by using tape strips 305-1, or other sterile tape, or using a different sequence of taping and unfolding. - After having the
drape 300 firmly engaged in its position and theu-shaped opening 305 in place around the surgical site of interest, the user may orient and/or fix the remaining portions of thedrape 300 with respect to the surgical table 100. - Next, the user may engage the
respective sleeve post 206 depending on whether a surgical procedure is being performed on the right hip or the left hip. For example, if the right hip is being operated, as shown inFIG. 1 , thesecond sleeve 304B is inserted or affixed to the square shapedpost 206. Whereas, if the left hip is being operated on as shown inFIG. 16D , then thefirst sleeve 304A is inserted or affixed to the square shapedpost 206. The inserting or affixing of therespective sleeve post 206, with the use ofhandles FIGS. 5 and 6 . Such inserting or affixing mechanism allows thedrape 300 to be positioned in place with respect to the table 300, thefemoral support hook 126 and theangled bracket 128. Thereby, ensuring that thedrape 300 is in place and does not move or reposition during the surgical procedure. - After the patient is fully draped and the
drape 300 is securely engaged to thepost 206, the user may then incorporate the sterileangled bracket 128 on top of thepost 206, as shown inFIGS. 16E and 16F , thereby sandwiching and securely engaging therespective sleeve post 206 and theangled bracket 128 and forming a sterile barrier between thepost 206 and theangled bracket 128. After positioning theangled bracket 128, therespective flap angled bracket 128 to act as a protective covering layer. For example, if the right hip is being operated on, as shown inFIG. 1 , thesecond flap 303B is engaged by the user. Whereas, if the left hip is being operated on as shown inFIGS. 16E-16F , then thefirst flap 303A is engaged by the user. By engaging thefirst flap 303A or thesecond flap 303B, the user is essentially folding back the flap on itself as shown in further detail inFIG. 16F . As discussed above with respect toFIG. 8 , in reference to thesecond flap 303B, the folding back of thesecond flap 303B results in the edge 303B4 folding back on itself to form a second barrier on thedrape 300 and theangled bracket 128 as the adhesive tape on the edge 303B4 attaches to itself and to thedrape 300. It is noted that only oneflap bracket 128 nearest thepost 206. In certain embodiments, edge 303B5 does not include adhesive so that thebracket 128 can rotate about thepost 206 during the surgical procedure without being restricted by theflap 303B. The edge 303B1 folds back on itself to form a second barrier on theangled bracket 128 and thedrape 300 as the adhesive tape on the edge 303B1 attaches to thedrape 300, and the adhesive tape on the edge 303B6 attaches to thedrape 300. Similarly, after the fold, the section 303B2 is adjacent to the distal end ofbracket 128, and does not include adhesive so that thebracket 128 can rotate about thepost 206 during the surgical procedure without being restricted by theflap 303B. - Such a folding and taping configuration allows an additional barrier layer of protection to be formed on the
angled bracket 128 and thetop surface 301 of thedrape 300. This ensures maintaining sterility and preventing or at least minimizing contamination. Thesleeve post 206, and theflap post 206 and the surgical procedure, for example, in case of a rip or tear in thesleeve - Thereafter,
femoral support hook 126 is installed into an appropriate opening on theangled bracket 128. Both, thefemoral support hook 126 and theangled bracket 128 are sterilized prior to each procedure. Thefemoral support hook 126 is a Food and Drug Administration (FDA) class 2 device as it contacts and supports the patient's femur bone. As discussed above with respect toFIG. 2 , a user is able to drive the femur lift mechanism orjack 124 up and down in order to adjust the elevation of thefemoral support hook 126. - Such unfolding and placement mechanism of the drape onto the table and surgical site ensures that the sterile segments of the drape and equipment used for the surgical procedure remain sterile, and are not contaminated by the non-sterile segments.
- It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. For example, various mechanical and electrical connection elements and actuators can be used to achieve the disclosed function. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
